  audio devices disappear, some programs freeze intermittently

Status in linux package in Ubuntu:

Bug description:
  Sometimes I notices that audio is suddenly interrupted and that all my audio 
devices are gone from the gnome-settings dialog. 
  When I run `aplay -L` it just hangs without output.

  After that event occured, all right-clicks (or interactions that bring up a 
context menu) in Firefox and Thunderbird and Chrome make the respective 
programs unresponsive. Interestingly, all programs that run at that time will 
be unresponsive from that moment onwards for at least a minute. That means a 
right-click in Firefox will also effect Thunderbird and vice-versa. During that 
phase of unresponsiveness, there are other programs (i.e. SublimeText) which 
strangely are uneffected by this. The frozen programs will eventually turn 
responsive for a short amount of time but subsequent interactions will always 
make them freeze again.
  I can't say that any specific event leads up to this. This happens randomly 
from time to time but at least once or twice a week. I'm always running 
Thunderbird, Firefox, Sublime Text, Sublime Merge, gnome-terminal.

  I'm using Ubuntu 5.3.0-21.22-generic 5.3.7 on Ubuntu 19.10. 
  As far as I remember, this issue is not specific to the 5.3.x kernels and 
also appeared before.
  The device is a Thinkpad X1 Carbon 6th Gen.

  I'm not sure which package causes this and my searches in the bugtracker 
didn't turn up issues that seem related, so I'm also unsure about what 
additional information to supply. Maybe one of you can guide me and I will 
gladly help with out with more information.
